Thanks. I read hdparm man several times but it was not clear for me that -d also reports dma status. For hdparm -d -c -u /dev/hdd I get:
/dev/hdd: IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on)
Typical.
Is this good or bad (for unmaskirq and IO_support)?
If it works for you, it should run faster to enable them. You can try, at worst you gain a shiny mug dish :-P
Probably. Bu why don't you use k3b instead of a windows in linux thing?
According to my knowledge neroLINUX is a native linux program.
I don't use it, haven't even tried, because I heard the contrary, and k3b and others work find for me.
I had several problems with k3b before. Unfortunately there is not a decent GUI cdburning software for linux. All of them ruins directory dates on burned media. But this would be a different topic.
Well...
1. What can cause that dma is turned off?
Check the kernel log.
Is the /var/log/messages file the kernel log? Or dmesg?
Depends. On most installations they go to /var/log/messages, others have a separate file.
I found lines in /var/log/messages like these:
kernel: hdc: irq timeout: status=0xd0 { Busy } kernel: ide: failed opcode was: unknown kernel: hdc: DMA disabled
This could be it.
I don't know which of these report problems and which are normal.
Difficult to say. I have a similar problem, when reading takes longer, or the door is open, and dma gets disabled in the process. I didn't have that problem before, so now I check the status just before doing a burn and enable it if necessary.
However recently I had also bootup problems. At certain point boot hangs and I have to reset. I can't remember the messages at which boot hangs (not always the same) but next time I will write it down. Couldit be a problem with the MB or bad wiring?
I have no idea at this point. - -- Cheers, Carlos E. R. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFFS0rJtTMYHG2NR9URAp+oAJ9oTRjBm4ZDts/bUxvub3FMD4x2gACfRPGs 4HQ3KqLg7iR1N2vLbUty7X0= =D5g+ -----END PGP SIGNATURE-----
